Leonard Schleifer is the CEO of Regeneron.
Noticing that the biotechnology company Genentech was conducting state-of-the-art research but not on diseases of the nervous system, Schleifer was determined to get into the biotechnology business.Choosing not to accept Gilman's efforts to recruit him as an academic, he found a sponsor in George Sing, a venture capitalist at Merrill Lynch, and obtained $1 million in seed capital.
He also recruited George Yancopoulos, a 28-year-old scientist, to be his partner, and in 1988 they founded Regeneron Pharmaceuticals. After several years of trying to recruit research doctors many of whom preferred to work in academia or for large corporations, they developed their first drug to treat Lou Gehrig’s disease. It was a failure as was their second drug to treat obesity. Thereafter, they invited the former Merck & Co. CEO Roy Vagelos to be the chairman of their company and to help to turn the company around. He implemented two strategic changes; only invest in drugs in which the biology of the disorder is fully understood; and do not underestimate the importance of human testing to ensure that what works in the laboratory will also work in the real world.
